Description

The present invention relates to a mask in which the length of the string hung on the ear can be adjusted.

The mask is worn on the user's face and is used to prevent pollen and viruses from entering and droplets from coughing and sneezing. A mask that can adjust the length of the string is being considered to match the user's face. For example, in the mask shown in Patent Document 1, the length of the ear strap is adjusted by attaching a support band to the mask body and sliding the ear strap in the gap between the support bands. Further, according to Patent Document 2, a mask in which a ring portion is provided on the side edge portion of the mask body and the ring portion is passed through an ear strap to adjust the mask is also considered (see Patent Document 2).

In both documents, the support band or ring may not be a stretchable material or may be made of a non-woven fabric, but both are ear hooks that pass through the support band or ring. It is common in that it uses frictional force to prevent the strings from slipping.

Registered Utility Model No. 3197181 Japanese Patent No. 6716644

According to Patent Document 1, one end of the ear strap through which the support band is passed hangs down and becomes an obstacle. Further, according to Patent Document 2, both ends of the ear strap are fixed to the side edge of the mask body, and unlike Patent Document 1, one end of the ear strap does not hang down. The remaining part of the ear strap that passes through the ring and is fixed to the side edge of the mask body is in a free state, and it is inevitable that it hangs down.

Further, in order to prevent the length-adjusted ear strap from loosening, it is important to strongly restrain the ear strap to the support band or the ring portion itself. In each patent document, it is also proposed that the support band is made of a stretchable material and that the inner surface is a friction surface by embossing. However, in order to add the function of strongly restraining the ear strap, there is a problem that a member or a material having such a function must be newly added.

In the present invention, the excess ear straps do not hang down as a result of length adjustment, and the ear straps are strongly restrained without adding another member or material to prevent the ear straps from loosening. It is an object of the present invention to provide a mask that can be prevented.

In order to achieve the above object, the mask of the present invention has a mask main body and ear hook portions on the left and right side sides of the mask main body, and the ear hook portion restrains the ear hook cord and the ear hook cord. It is provided with a string threading ring through which the ear hook string is passed without being sewn, the base end portion of the ear hook string is sewn to one end of a side portion of the mask body, and the string threading ring is a side portion of the same side of the mask body. At the tip of the ear hook string sewn to the other end of the ear hook and passed through the string threading ring, a ring surrounding the middle of the ear hook string is formed, and the ear hook string is sewn in a tightened state. The ring is fixed and formed into a restraint ring.

According to the mask of this invention, the excess ear straps do not hang down as a result of length adjustment, and the ear straps are strongly restrained to prevent slack without adding new members or materials. it can.

It is a figure which shows the mask of this Example, FIG. 1A is a front view, and FIG. 1B is a usage state diagram. It is explanatory drawing which shows the manufacturing process of the mask which concerns on this invention. It is explanatory drawing which shows the process of making the adjustment part of an ear strap.

In FIG. 1, the mask 1 of this embodiment has a mask main body 2 and an ear hook portion 3. The mask body 2 is a part used to cover the user's mouth and nose. The mask body 2 is three-dimensionally formed, and is configured so that when the user wears the mask 1, the central portion of the mask body 2 is separated from the user's face. The mask body 2 has an exodermis and an endothelium, and a filter may be provided between them. The exodermis may be a resin such as a woven fabric, a knitted fabric, a non-woven fabric, or polypropylene. The same applies to the endothelium.

Ear hooks 3 are provided on the left and right sides of the mask body 2. The ear hook portion 3 includes an ear hook string 4 and a string loop 5 through which the ear hook string 4 is passed without being restrained. As the ear strap 4, a stretchable band is used. For example, a rubber cord is composed of a thread and an elastic thread, and the material of the thread is a polyester thread, a synthetic fiber of a nylon thread, or a natural fiber, and the material of the elastic thread is a polyurethane elastic thread or a natural rubber thread. It is suitable as an ear hook string 4. In this embodiment, a flat rubber made of a thread and an elastic thread was used as the ear strap 4.

The string threading ring 5 is formed by forming a band into a ring shape and sewing both ends thereof to one end (lower end 2b in the embodiment) of the side side portion of the mask body 2. The inner diameter of the string loop 5 is larger than that of the ear strap 4, and the cord loop 5 does not restrain the ear strap 4 within the diameter. In this embodiment, the string loop 5 is made of the same material as the ear strap 4, but as long as the ear strap 4 can pass through, the string loop 5 is not limited to the string, but is made of a resin, a metal ring, or a tube. You may use another material such as.

One end (base end 4a) of the ear strap 4 is sewn to the other ends (upper end 2a in the embodiment) of the left and right side edges of the mask body 2, and is below the side edge on the same side. It penetrates the string threading ring 5 provided at the side end 2b. The other end of the ear strap 4 is processed into a restraint ring 6 as described with reference to FIG. 3, and restrains the ear strap 4.

FIG. 2 is an explanatory view for creating the mask 1. First, the base end portion 4a of the ear strap 4 is sewn to the upper end portion 2a of the side side portion of the mask body 2. On the other hand, the string loop 5 is sewn to the lower end 2b of the side side portion by bending a short band in the middle to form a space through which the ear strap 4 passes (FIG. 2A).

The other end (tip 4b) of the ear strap 4 is passed through the strap ring 5 (FIG. 2B). Then, the tip portion 4b is hung in the middle of the ear strap 4, folded back into a ring surrounding the ear strap 4, and sewn to form a restraint ring 6 (FIG. 2C).

FIG. 3 is an explanatory diagram for creating the restraint ring 6, and shows a process for sewing the restraint ring 6. The tip 4b of the ear strap 4 is hung in the middle of the ear strap 4 (FIG. 3A), and the ear strap 4 is surrounded by the tip 4b. Then, in order to fix this shape and form the restraint ring 6, the position 6a for closing the enclosure is sewn, and at that time, the ear hook string 4 and the tip portion 4b are pulled from each other and sewn (sewn). FIG. 3B). This is to prevent the middle part of the ear strap 4 from being sewn to the tip portion 4b. The inner circumference of the restraint ring 6 is made smaller than the diameter of the ear strap 4 by sewing in the pulled state. In this embodiment, flat rubber is used as the ear strap 4, but it may be smaller than the width of the flat rubber. When the pull is returned, the restraint ring 6 fastens and stays on the ear strap 4 (FIG. 3C). Both the restraint ring 6 and the ear hook cord 4 are the same rubber cord, and the restraint force by the restraint ring 6 can be strengthened. In this embodiment, the flat rubber is used as the ear strap 4 in order to facilitate the workability of sewing.

If the tip portion 4b is cut at the sewn portion of the restraint ring 6 leaving a seam allowance, it does not get in the way. The restraint ring 6 can be moved over almost the entire length from the base end portion 4a of the ear strap 4 to the string loop 5, and the length of the ear strap 4 can be adjusted.

FIG. 1B shows the form of the ear hook portion 3 when the user wears the mask 1. The ear strap 4 folded back from the string loop 5 is folded straight back to the position where the restraint ring 6 restrains the ear strap 4. Since the stringing ring 5 does not restrain the ear hooking string 5, the ear hanging string 5 left over as a result of the adjustment is lined up in parallel between the stringing ring 5 and the restraining ring 6 with the same length. In this way, the problem that the excess ear strap 4 hangs down is solved. Further, the restraint ring 6 is a part of the ear strap 4, and has an effect that the ear strap can be strongly restrained to prevent slack without newly adding another member or material.

In the above embodiment, flat rubber is used as the rubber cord of the ear strap 4, but round rubber may be used. Further, a band having elasticity such as polyurethane may be used. Further, the base end portion 4a of the ear strap 4 may be sewn to the mask body to the lower end 2b of the side side portion, and the string threading ring 5 may be sewn to the upper end 2a.
